It is 22 mm.

Great to read that it turned out so well for you!

One fact, however, stands to be corrected:

" I also understand that the watch inside and out should be fully black so no scratches should appear."

This is not correct. Ceratanium is a material with a titanium alloy in its core and a black ceramic transformation layer on top. So theoretically, although extremely difficult, it is possible to scratch the black layer and reveal the silver titanium alloy below.

The only material that is black inside and out is black ceramic.

I can only repeat my advice: If you want to be sure you should bring it to an AD.

Or, as an alternative: You could write an e-mail to the concierge and ask if the serial number on the caseback matches the type of your watch (Pilot's Chronograph Le Petit Prince). I am quite sure it does not...

What do you mean by "I recently had...."? Is it yours? Did you buy it (for an incredible low price)? Did you own it and then sell it? Did you see it somewhere?

I am very cautious about answering questions like yours, especially if supported with poor photography. We do not want to help the counterfeiters improve their products.

My advice to you: bring it to an authorised IWC dealer. They will help you for sure.

A lot of doubts here. As Tonny and you already mentioned, the dial does not fit to the rubber coated case.

The case back engraving is wrong on multiple levels, too. First, the typeface is wrong. Then, the Boutique edition (Ref. 390208) was limited to 250 and not 1000 pieces. "Edition 2011" is not engraved in the original version.

I would stay away from this watch.

Hi Dave,

Welcome to the Forum!

Theoretically it could be done. However, there are several drawbacks:

1) The strap would be 1 mm slimmer than your standard one and this would be visible between the lugs. Of course it depends on personal taste whether or not you can live with it.

2) If you would like to attach the strap you mentioned you would have to change the buckle. Your standard strap has a deployant buckle whereas the green rubber strap is made for a pin buckle.

3) You would also (most probably) have to change the spring bars. Your standard spring bars have a bigger diameter than the spring bars for the green strap. It would be difficult or even impossible to mount the green rubber strap on the thicker spring bars.

Im adding to this thread a sad information that might be of interest for some of the collectors:

Hano Burtscher passed away on the 22nd of May 2023. I am quoting a local newspaper called "Poschtli" (automated translation from German):

In memory of HANO BURTSCHER Schaffhausen/Thusis (1946 to 2023)

The Burtscher-Muoth family (coming from Pontresina) settled in Thusis in 1952. Father Burtscher worked in the Emser-Werken, his wife took care of the household for the family of five with son Hano and the two daughters Julitta and Rita. After primary and secondary school in Thusis, Hano completed a four-year apprenticeship as a machine draftsman in the Emser workcn. Along the way, he discovered a love of painting and music, especially jazz, as a balance to his precision-demanding work. On the clarinet and alto saxophone he played with his friends mainly Dixieland and Swing.

After successfully completing his apprenticeship, he was drawn to Biel to apply his talent for drawing at the renowned watch company Omega. It was in Biel that he met his future wife Elisabeth. In 1973, the couple moved to Schaffhausen with their two sons Faro and Michael, where Hano left a lasting mark at IWC, first as a technical draftsman and then as an extremely creative watch designer. Hano still designed the famous Da Vinci collection in pencil and ink. In his spare time, he painted incessantly and listened to a lot of music.

Over 3000 long-playing records and several hundred Kcvox tapes testify to his love of jazz and classical music. In 1998 Ilano was elected the 67th Munot guardian. At the same time, his wife Elisabeth looked after the deer colony living there. A portrait of Burtscher and his many tasks on the Munot, a Schaffhausen landmark, was shown on Swiss television on 7 September.

December 1998 in an article that received much attention at the time. In recent years, Hano had struggled with several insidious diseases. On May 22, his strength finally left him. We will remember his friendship, his unconventional playing while improvising on the clarinet and saxophone, and his many artistically skillful and original paintings.

The obituary was written by Gieri Battaglia.

You can now buy 30 different ones in the IWC Museum in Schaffhausen (3 CHF
each). However not as posters but as postcards only.

There are all the old ones but also more modern ones for ladies watches (not
as funny as the old chauvinist ones, in my opinion :-))

I have a friend who was also not happy with the original strap of the 389101.
In addition, his strap started to degrade just half a year after he acquired
the watch.

He replaced it by the strap of the Ceratanium Double Chronograph Ref. 371815
and is totally happy with it. I personally think that it is a perfect fit. The
only thing is that this strap is made for a pin buckle and not for the
original deployant clasp. But for my friend this was also the preferred
option.

Nice TV Jumbo!

And of course we do love the 70ies!

Wow, the platinum 5005 - an absolutely fantastic "badass" watch! I had the
steel version on a steel bracelet but sold it some years ago because it was
just too big for my skinny wrists.

My current watch is certainly less badass but a rare bird as well:

I am not sure if the Ingenieur watches are made for climbing and alpinism. But
for my ascent to the Matterhorn I absolutely had to wear a watch. So I
decided to bring my 3239 Laureus to the summit.

There was one not too long ago:

Pallweber Pocket Watch

I agree that it is Ref. 3700. I own one with the same "full signature dial".
However, mine also has a "TITAN" inscription on the case:

I don't know why but it is as it is.

I also own several IWCs, including Portugiesers, and none of them winds anti-
clockwise. Nevertheless, the new Caliber 82 does.
